Tones were recognised by Greek philosopher Aristoxenus (375-335 BCE), who called them 'tensions'.Although meditation, yoga and taking naps are effective forms of stress relief, listening to music is one of the easiest ways to get your dopamine flowing.

In music, notes are assigned to tones with different fundamental frequencies, in order to describe the pitch of played tones. The fundamental frequency determines the pitch of the tone, which is perceived by the human hearing.

The common denominator frequency, which is also often the lowest of these frequencies is the fundamental frequency, and is also the inverse of the period of the waveform. The Fourier theorem states that any periodic waveform can be approximated as closely as desired as the sum of a series of sine waves with frequencies in a harmonic series and at specific phase relationships to each other. A complex tone is a combination of two or more pure tones that have a periodic pattern of repetition, unless specified otherwise. The notes used in music can be more complex than musical tones, as they may include aperiodic aspects, such as attack transients, vibrato, and envelope modulation.Ī simple tone, or pure tone, has a sinusoidal waveform.

A musical tone is characterized by its duration, pitch, intensity (or loudness), and timbre (or quality). Traditionally in Western music, a musical tone is a steady periodic sound. This notation indicates differing pitch, dynamics, articulation, instrumentation, timbre, and rhythm (duration and onset/order).
